Scientism is a philosophy which purports to define what the world ‘really is’. It adopts what the philosopher Thomas Nagel called ‘an epistemological criterion of reality’, defining what is real as that which can be discovered by certain quite specific methods of investigation. As a consequence all features of experience not revealed by those methods are deemed ‘subjective’ in a way that suggests they are either not real, or lie beyond the scope of meaningful rational inquiry. This devalues capacities that (...) (we argue) are in fact essential components of good reasoning and virtuous practice. Ultimately, the implications of scientism for statements of value undermine value-judgements essential for science itself to have a sound basis. Scientism has implications, therefore, for ontology, epistemology and also for which claims we can assert as objective truths about the world. Adopting scientism as a world view will have consequences for reasoning and decision-making in clinical and other contexts. We analyse the implications of this approach and conclude that we need to reject scientism if we are to avoid stifling virtuous practice and to develop richer conceptions of human reasoning.

Discussions of diagnosis in mental illness are still beset by the suspicion that ‘value judgements’ are in some special sense ‘subjective’. The history of the debate about the reality of mental illness has seen a divide between those who accept that diagnosis is ‘value-laden’ and therefore accept a relativist/subjectivist account of mental illness, and those who feel the need to deny the value-laden nature of diagnosis to defend the reality of mental illness. More nuanced analyses note that all medical diagnosis (...) is arguably value-laden & this does not imply that medical conditions are unreal. All judgement requires a subject, but it does not follow that it is ‘subjective’ in any sense implying ontological relativity. The implications are substantial: either all medical judgement is relative or realism about value is true. To justify our claims in diagnosis, we need to discuss and defend our value-judgements. We must reject ‘scientism’ for an openly value-laden account of human functioning. Medical epistemology requires value-realism. The contentious nature of the value-judgements in the case of mental illness should not mislead us into concluding they are relative. (shrink)

Effective person-centred care requires recognition of the personhood not only of patients but of practitioners. This chapter explores the consequences of this recognition for major debates in medical epistemology, regarding clinical reasoning and the relationship between research and practice. For too long these debates have been dominated by false dichotomies - subjectivity versus objectivity, judgement versus evidence, reason versus emotion. Based on flawed understandings of such core concepts as “objectivity” and “engagement”, this distorted dissection of the subject-object relationship has served (...) to depersonalise practice. The costs of this depersonalisation include over-regulation and micromanagement of healthcare processes by administrators and payers at the same time that information from clinical research remains under-utilized and the personhood of patients risks being ignored. Science is a human practice, founded in a broader conception of human reasoning, ontologically dependent on human beings living and engaging with the world in social, emotional and ethical contexts. After looking at different conceptions of epistemic hierarchies and their uses in the analysis and evaluation of reasoning in a range of practice contexts, we propose a “nested hierarchy” that effectively turns upside-down the flawed evidence hierarchies that have helped to depersonalise care. T.S. Eliot’s “wisdom, knowledge, information” scheme (to which we add “data” below “information”) provides a model for a person-centred epistemic hierarchy. This crucial, person-centred inversion represents levels of awareness that characterise more or less developed thinking and judgement on the part of the particular practitioner. (shrink)
